Wash and pick over the beans. Cover with water and soak overnight; drain.

Heat the oil in a large pot. Add the onion and saute until tender, about 5 minutes. Add the chili powder, salt, beans, and 5 cups water. Bring to a boil. Reduce the heat, cover, and simmer until the beans are tender, 1 to 1 1/2 hours.

Add the green chili sauce; stir and simmer, uncovered, 30 minutes longer. If the mixture is too soupy, simmer a few minutes longer to reduce the liquid.
